常用数据结构Lua中的table不是一种简单的数据结构，它可以作为其它数据结构的基础。如数组、记录、线性表、队列和集合等，在Lua中都可以通过table来表示。 一、数组在lua中通过整数下标访问表中的元素即可简单的实现数组。并且数组不必事先指定大小，大小可以随需要动态的增长。 12345678a = &#123;&#125;for i = 1,100 do a[i] =

在Lua中习惯上数组的下表从1开始，Lua的标准库与此习惯保持一致，因此如果你的数组下标也是从1开始你就可以直接使用标准库的函数，否则就无法直接使用。 二、二维数组Lua中主要有两种表示矩阵的方法，第一种是用数组的数组表示。也就是说一个表的元素是另一个表。 ...</div></div></div><div class="recent-post-item"
